23 Claims.

The present invention relates to -clothes wringers and refersparticularly to the disap: pearing type of wringer arranged with awringer mounting to permit the wringer to move into an inoperativeposition inside the tub of an ordinary domestic washing machine.

It is recognized that in the prior art numerous attempts have been madeto provide a disappearing wringer of this general class, but to the bestof the applicants knowledge none of the prior art structures have beenin any way successi'ul and none have been accorded commercialrecognition. It is believed that this fact results from the deficienciesof the prior art structures since each of these known to theapplicant-requires that the tub be made with extra space to accommodatethe wringer, and in most instances the wringer mounting or certain partsthereof have been mounted inside of the washing machine tub.

In the present state of the industry practically all manufacturers havediscarded the several old types of washing machines and havestandardized on a small tub, bottom agitator model, which is not suitedto the disappearing wringer structures known in the priorart.

It is, therefore, a principal object of this invention to provide awringer mounting shiftable between the operating position above the rimof a washing machine tub and an inoperative position inside of the tub.In this connection this invention also aims to provide a structurewherein the wringer may be easily manipulated between the two positionsand wherein the mounting includes means to guide the wringer into exactpredetermined position with respect to the tub as the shifting occurs.

Another object of the invention is to provide a disappearing typewringer in connection with a washing machine having a smooth,uninterrupted, regularly formed interior surface of the washing machinetub, to the end that the tub may be easily cleaned and that the washingaction of the machine will not be hindered.

A further object of the invention is to provide a disappearing typewringer mounted on a supported column positioned exterior ofthe washingmachine tub and extending downwardly below the bottom wall of the tub inorder that the driving motor for the agitator of the washing machine mayalso drive the wringer rolls.

A further object of the invention is to provide a disappearing wringerand washing machine cover arranged to provide a smooth uninterruptedtable top surface.

Other objects will appear hereinafter.

These objects are accomplished in the present invention by the provisionof a telescoping wringer drive column extending upwardly from theagitator gear housing outside of the side walls of the washer tub. Atthe upper extremity of the telescoping column any ordinary type ofwringer may be mounted on a mounting bracket including a vertical cfisetposition to extend over the rim of the tub. Thus, when the wringer ishoused within the tub, it is supported by the vertical column on theouter wall of the tub, the arm portion extending more or lesshorizontally across the tub rim and the mounting bracket dependingdownwardly from the arm inside of the tub.

The general washing machine structure The usual type of modern washingmachine includes a more or less cylindrical tub ll having a bottom wallI! and a surrounding side wall i3 terminating in an annular rimil. Anagitator 15 including a central'column l6 and a plurality of agitatorvanes I1 is mounted on a drive shaft i8 extending upwardly through thelower wall I! of the tub and from a gear housing I9 which normallyincludes a reduction gearing and an oscillating agitator drivemechanism. A motor 2| operates through the mesupporting bracket dium ofa V-belt 22 to impart rotary driving movement "to a pulley 23 on theshaft 24 of a gear housing l9.

The mechanism thus far described has been found to provide a veryeflicient and generally satisfactory washing machine and has beenadopted by practically every manufacturer to the exclusion of thevarious other types of machines, as, for example, the old oscillatingdrum, suction cup, or dolly-type mechanisms. However, to obtain maximumefliciency of the mechanism, it is essential that the tub and agitatorbe dimensioned to very carefully calculated proportions, and it is alsoessential that the interior walls, of the tub be smooth, regular andunobstructed. This is essential, of course, as a practical matter tofacilitate cleaning of the tub after use, but it is also essential inorder to permit proper water action and uniform water circulationthroughout the entire tub area.

In addition to the essential washing machine elements heretoforedescribed, the preferred embodiment of the invention illustratedincludes a housing 26 comprising four wall panels terminating atapproximately the same height as the rim Id of the tub II andinterconnected with the tub rim by horizontal portions 21. In thepresent structure this housing 26 acts as the supporting frame for thetub and driving mechanism, but it is understood that any other type ofsupporting frame may also be used.

Preferred wringer mounting The wringer 3| illustrated in connection withthe preferred embodiment of the invention includes a lower frame 32, anupper frame 33, a pair of cooperating wringer rolls 34 and 35, andfolding drain boards 36. The lower frame 32 includes a pair of flanges31, which may be secured to a wringer mounting bracket 38 in any desiredway, as for example, by means of the mounting screws 39. It will be seenfrom examination of Fig. 2 that the mounting bracket 38 extends directlyupwardly from the flanges 31 and includes an integral horizontal armportion 4| extending laterally from the bracket 38 to the telescopingwringer column 42. The wringer column .42 includes a sliding tubularmember 43 extending downwardly through a flange 44, carried by thestamping 44' attached to the horizontal surface 21 of the washingmachine frame and a flange 45 carried on the 46. A shoulder ring 45'fixed on the tube 43 stops the wringer in its upper position by contactwith the flange 45. The bracket 46 is positioned in the space outside ofthe vertical side wall |3 of the tub I2 and inside of the walls of theouter housing 26 and is secured in position by ears 4'l welded to thetub and housing. The bracket 38 with its arm portion 4| supported on thetubular column 42 have the vertical portions thereof spaced from eachother and form a substantially inverted U-shaped structure with a neckgap therein to clear the wall of the tub while the wringer is storedwith'n the tub.

Driving power is transmitted from the motor 2| to the rolls 34 and 35 ofthe wringer 3| by mechanical driving connections extending from the gearhousing l9 upwardly through the tele-' scoping wringer housing 42,thence horizontally through the arm 4| and downwardly through themounting bracket 38 to the shaft of the lower wringer roll 35. Thisstructure is illustrated in detail in Fig. 4 and includes a verticaladjacent its upper end.

A sliding driving connection between the shaft 5| and the tube 54 isestablished by the cross pin 51 mounted in the vertical shaft 5| andadapted to engage a pair of opposite longitudinal slots 58 in the wallsof the sleeve 54. A bevel driving gear 6| is mounted at the extremeupper end of the sleeve 54 and is adapted to be engaged by beveleddriven gears 62 and 63, each of which is mounted in sliding non-rotatingrelationship on horizontal drive shaft 64, which extends between thebearings 65 and 66 formed integral with the top arm 4| of the wringersupport.' This reversing mechanism is of conventional design and willnot be described in detail except to point; out that by the manipulationof the reversing handle 61, the gears 62 and 63 may be shiftedlongitudinally on the shaft 64 so that either gear may engage thedriving pinion 6| and establish forward or reverse driving connectionsto the wringer,

The driving connections to the wringer 3| are completed by a gear trainextending downwardly through the mounting bracket 38 and including adriving gear 68 keyed to the shaft 64, an intermediate gear 69 mountedonthe stud 'II and a driven gear 12 including a notched driving sleeve13 mounted on a stud 14. The notched driving sleeve 13 is of properdimensions to engage, and establish driving connection with, the lowerroll shaft of the wringer 3|. Bolt holes 15 and 16 are provided in thewalls of the mounting bracket 38 and are positioned to locate the driveshaft of the roll 35 in proper alignment with the driving sleeve 13. Inthis connection it might be pointed out that in the present state of theart, the dimensions of wringers have been quite well standardized, andthe bracket here illustrated permits a standard type of wringer to beused.

In the operation of the mechanism it is essential that facilities beprovided to guide the wringer into exact predetermined position in thetub for the reason that the wringer is of considerable mass and couldnot be satisfactorily housed within the tub unless adequate provision ismade to prevent the wringer from striking the side walls of the tub anddamaging the enamel or from striking the agitator and possibly damagingor be moved into and out of position with some degree of precision toaccomplish the close nesting essential to the satisfactory use of thedevice.

To guide the wringer into nesting position, the telescoping wringercolumn 42 is provided with a key 8| riveted to the tube 43 by aplurality of rivets 82, the key 8| being longitudinally slidable in akeyway 83 cut in the wall of the upper flange 44. The relative positionsof the key 8| and the keyway 83 are such that the wringer will bepositioned in exactly the correct angular relationship with the tubbefore it can be moved downwardly and will thus be guided into exactpredetermined nested position inside of the tub.

It will be noted that the weight of the wringer most position.Preferably the spring 84 is 'of' sufficient size to overcome the entireweight of the wringer and lift it to its uppermost position.

Thus, when the operator desires to position the wringer inside of thetub she will move it downwardly against the force exerted by the springand lock it in its lowermost position by means of the spring-pressedplunger 85 mounted in the sleeve 44 and arranged to register with thelowered locking orifice 81 in the tube 43. When the wringer is thuslocked in its lowermost position, the machine cover 86 may be placedon-the tub to provide a smooth, uninterrupted table top surface, asillustrated in Figs, 1 and 4.

To raise the wringer to its operating position, the cover 86 should beremoved'and the plunger 85 withdrawn to allow the spring! to lift thewringer to itsuppermost operating position, as illustrated in Fig. 2. Itwill be noted that the length of the key BI is such that it iscompletely 3 above the water line'of the tub 9| that there is no dangerof splashing'or overflow through the withdrawn from the keyway 83 asthe'wringer reaches its uppermost position, in order that the wringercolumn may be swung to any one of a number of angular positions withrespect to the and so that it will be guided into the tub by the key 8|.

Modified mounting structure A modified form of the wringer mountingstruc-- ture is illustrated in Fig. 6. In this structure it will be seenthat the supporting v arm for the wringer includes 'a vertical ofiset toextend upwardly above the rim of the tub and downwardly inside the tubto the wringer in much the same manner as the structure heretoforedescribed and parts. However, the driving connections to the wringerroll are not carried upwardly through this vertical offset bracket, butare established directly between the wringer driving column and thewringer rolls.

illustrated by parts 38, 4|, 43 and'companion The structure illustratedin Fig. 6 includes the a tub 9| and agitator 92. A telescoping wringercolumn 93 is mounted in vertical position immediately outside of thevertical side walls of the tub 9| and includes a stationary outer sleeve94 and a vertically slidable inner sleeve 95 mounted therein. At theupper extremity of the sleeve 95 a vertical offset bracket- 96 isprovided and the bracket 96 includes a horizontally extending armportion 91 and a downwardly extending mounting bracket 98 on which thewringer 99 may be mounted.

The tub 9| is provided with a cover I8I having a slightly raised portionI82 to enclose the arm 91 and a notch I83 is cut in'the vertical sidewall I84 of the cover to accommodate the arm. It will notch when thewringer'is raised and the washing machine is in operation.

The driving connection to the wringer is established by a'drivingshaftI86 the lower end of which is in telescoping relationship with the powerdriving means (not shown) and the upper end of whichcarries a drivingpinion I81 journalled for rotation in a bearing I88 carried in thebracket I89 afllxed to the inner walls of the vertically movable sleeve95.-

A pair of reversing gears 7 III and II2 are.

- on a sleeve I I5. The shifting clutch element II6 keyed to the sleeveII5 may be shifted by means of a reversing control (not. shown) toestablish driving connection between either of the reversing gears andthe sleeve 'I I5. 7

The driving connection betweenvthe sleeve I I5 and the lower wringerroll II6 of the wringer 99 is completed by means of a longitudinalsliding drive shaft II'I housed within the tubular shaft II8 of. thewringer roll and held in .splined rela-' tionship with the r011 by thehexagonal splines be seen that this completes the power drive connectionto the wringer, since power transmitted from the vertical drive shaftI86 will cause the driving pinion, I81 to. drive the gears III and H2,while the'clutch element 6 will couple one of these gears to the sleeve5 and thence to the sliding drive shaft I I1 and the lower wnn' ger roll6.

When the operator desires to lower this wringer structure into the tub,it is, of course, necessary that the sliding shaft I I! be withdrawninto telescoping relationship with the lower roll in order that it willnot strike the upper annular rim of the tub as the wringer is lowered.To accomplish this result, a telescoping tube and plunger 'is arrangedwithin the sleeve 5 by which the operator may force the telescopingdrive shaft II'I into inoperative position. The plunger arrangementincludes a tube I25 fitted within the sleeve 5 and provided withalongitudinal slot I26 having a bayonet portion I21 adjacent its extremeleft end.'- An actuating plunger I28 is fitted within the tube I25 andis provided with ancross1pin I29 positioned to slide in the slotAssuming now that the operator wishes to disengage the drivingconnection preparatory to lowering the wringer into nested position withbe noted that this leaves practically the entire a surface of themachine cover smooth and flat and available for use as a table top andthat the notch I83 is in a vertical portion of the cover wall where itis quite inconspicuous even when the wringer is lifted to its operatingposition. Further, the notch I83 is, so small and so far the tub, shemay grasp the knob I3I affixed to theextreme left end of the plunger I28and draw it outwardly to the left untilthe cross pin I29 reaches theextreme left end of the slot I26. At this point she will rotate the rodI28 8, fraction of a revolution to lock the cross pin I29 and thebayonet portion I21 of the slot and move the knob I3I back to theposition shown in the drawings.

- This action will cause thetube I25 to-bear against the end portion ofthe shaft 1 and force it into telescoping relationship with the lowerwringer roll ,6, and, as the shaft reaches the position illustrated inthe drawings, the sliding latch -member I32 will drop by gravity toengage the notch between the hexagonal portion of the notch I I1 and thereduced pilot portion I23. When this occurs the tube I25 may bewithdrawn into the sleeve H and the wringer may be lowered into nestedposition within the tub.

When the wringer is again raised into operation position, the drivingconnections may be reestablished by simply lifting the latch I32 bymeans of the finger portion I33 provided for the purpose and at thattime the spring I2I will snap the shaft II1 to the left to re-establishdriving connection to the wringer.

It is, of course, desirable that the arm 91 be of relatively small crosssection in order that it be inconspicuous'when the machine is closed,but it is also essential that the wringer mounting be of sufficientstrength to provide a solid support for the wringer when in itsoperating position. To permit the use of a supporting arm of unusuallysmall cross section, it is contemplated that a. shiftable brace memberI34 may be pivotally mounted at I35 and arranged to swing between aninoperative position I36, and a supporting position I31. It will beunderstood, of course, that the support will be moved to position I36when the wringer is lowered into the machine tub and when the wringer islifted to its operating position above the tub, the support may be movedto the position I31 wherein it will contact the sleeve 95 and lendadditional support to the lower end of the wringer mounting bracket 98.

stood, of course, that the sprocket I48 may be geared to the pressurerolls of the wringer MI by the use of any conventional powertransmission mechanism (not shown). This transmission may also beprovided by a train of spur gears in place of the chain transmission.

The cover for the square tub machine illustrated in Fig. 8 is shown inFig. 9 and includes a body portion I5I of shape and dimensions to fitthe tub I45 and a shiftable comer extension I52 mounted in slidingrelationship with the main cover I5I and adapted to be shifted betweensolid line position in which the body portion I52 will extend over thelateral ofiset mounting I44 and the wringer column I43 and the dottedline posi-' tion indicated at I53 in which the shiftable section I52will completely close the tub when the wringer MI is lifted to operatingposition. To facilitate manual shifting of the section I52 a button I54is provided and the button I54 extends upwardly through a longitudinalslot I55 in the cover I5I.

While the lateral oifset mounting is particularly adapted for use with asquare tub machine, its use is not limited thereto and it may be used toequal advantage on a round tub. When used with the round tub it ispreferable to provide a cover I51 (Fig. 12), including a cut-awaynotched portion I58 to accommodate the arm I44. However,

when the wringer MI is raised to its operating position, the opening I58may be closed by a shiftable sliding door I59 secured to the cover I51by a screw I60. See Figs. 10, 11, and 12.

In any event, a limited amount of torsional fiexing may take place inthe arm, but this is not objectionable in the structure shown in Fig. 6,forthe driving train does not extend through the arm.

In the form of the invention shown in Fig. 4, the flexing may also takeplace, but the twisting will be co-axial with the shaft 84 and will notinterfere with its action. Similarly, the chain drive shown in Fig. 8and hereinafter described will 'operate with entire satisfaction,notwithstanding a certain degree of flexing of the arm.

The lateral ofiset mounting In thestructure illustrated in Fig. 8 thewringer MI is mounted on a bracket I42 interconnected to a telescopingcolumn I43'by means of an arm I44 substantially similar to thesupporting brackets, columns, and arms heretofore described andillustrated by parts 8|, 84, 85, 81 and companion parts. However, itwill be noted that the arm I44 extends angularly away from the centerline of the wringer MI and thus provides a lateral offset for thesupport. This construction is particularly advantageous when it is usedin connection with a square tub machine, as for example, a machinehaving a square tub I45 in which the typical agitator I46 is mounted, Inthis connection it should be pointed out that in a square tube machineit is customary and desirable to position the wringer supporting columnat one corner of the tub and that the lateral off- Operation Assumingthat the preferred embodiment of the invention illustrated in Figs. 1 to5, inclusive, is in its inoperative, or closed position illustrated inFig. 1, the mode of operation is as follows:

The operatorwill first remove the cover 86 and will then withdraw thespring plunger to perniit the lifting spring 84 to raise the wringerstructure 3I out of the tub and to the uppermost position of thetelescoping wringer column 42. As the wringer reaches this position thekey BI is withdrawn from the keyway 83 and the wringer may be swungaround the column 42 to be indexed and locked in any position about thespringpressed plunger 85 which may seat in any one of the indexingopenings 81 in the tube 43.

The wringer may now be operated in either forward or reverse position bymoving the manual shifting control 61 into either position to com-' way83. The wringer may then be moved downwardly against the action of thelifting spring 84 and as the wringer moves into the tub, it will beguided into exact predetermined position between the tub side walls andthe agitator by means of the key 8I. As the wringer reaches itslowermost position the spring-pressed plunger 85 will spring into thelocking orifice 81 in the tube 43 and will maintain the wringer inlowered position until the plunger is again withdrawn by the operator.

The structure illustrated in Fig. 6 may be op- I erated in exactly thesame manner with the exception that the latch I 32 must be'manuallylifted to permit the compression spring III to snap the hexagonal driveshaft II! into coupled connection with the driving sleeve I l 5. Also,when the operator wishes to again lower the machine into the tub, thedrive shaft Il'l must be telescoped into the lower wringer roll bywithdrawing the plunger I28, latching the pin I29 in the bayonet slotI21, and then moving the rod I28 to the right, as viewed in the drawingsto cause and an operating position above the upper rim of the tub. Byutilizing the guiding means illustrated and disclosed inthisapplication, it is entirely feasible to use a full size wringer inconnection with a washing machine tub of ordinary dimensions and it isunecessary to provide extra housing space for the wringer.

Further, it will be seen that the use of the exterior driving columndisclosed by this appli-' cation permits the use of a driving motorcommon to the wringer and to the agitator of the washing machine andalso provides a washing.
